PROBLEM TO BE SOLVED: To provide an image forming apparatus using a rotary developing system where the electrical connected state between a connection part to be fed in terms of power on a developing device side to which developing voltage is applied and a power feeding connection part on a main body side is stabilized to prevent the shaving and the damage of a member constituting the connection part and a leak phenomenon caused by separation when the connection part abuts on. SOLUTION: In the image forming apparatus having the power feeding connection part 13 freely electrically connected to the respective connection parts to be fed in terms of power 52 provided in a plurality of developing devices 5, either the connection part 52 or the connection part 13 has a rotating body 52 driven to freely rotate by the other.
